2. Matching Flow Cytometry Reagents to Instrument Specifications
Choosing the right flow cytometry reagents is key to a successful analysis. It’s important to know the flow cytometer’s strengths and limits. Also, understanding the reagents’ characteristics is essential.
2.1 Aligning Excitation and Emission Profiles with Laser Configurations
First, match the excitation and emission profiles of the fluorochromes with the flow cytometer’s lasers. Flow cytometers have lasers that emit light at specific wavelengths. These wavelengths excite the fluorochromes attached to cells or particles.
For the best results, the excitation spectrum of the fluorochrome should match the laser’s wavelength. For example, if a flow cytometer has a 488nm laser, use fluorochromes like FITC or PE. Also, make sure the emission spectrum of the fluorochrome doesn’t overlap with other fluorochromes in a multicolor panel.
2.2 Optimizing Reagent Selection for Sony Flow Cytometry Platforms
Sony flow cytometry platforms are known for their advanced features and flexibility. When picking reagents for these platforms, consider the laser configurations and detector setups. Sony flow cytometers have a variety of lasers, like 355nm, 405nm, 488nm, and 561nm. This allows for exciting a wide range of fluorochromes.
For instance, a Sony flow cytometer with a 405nm laser can use fluorochromes like BV421 or Pacific Blue. Also, use PC Cy7 or PC Dye conjugates for panels that need to detect multiple markers at once.
- Consider the laser configurations available on the Sony flow cytometer.
- Choose fluorochromes that are excited by the available laser wavelengths.
- Ensure the emission spectra of the chosen fluorochromes are well-separated to minimize spectral overlap.
2.3 Building High-Dimensional Panels with 30-40 Fluorescent Colors
Creating high-dimensional panels with 30-40 fluorescent colors is complex. It requires careful planning and optimization. We need to pick fluorochromes that match the available lasers and can be detected by the flow cytometer’s detectors.
To do this, start by identifying the markers of interest. Then, choose fluorochrome conjugates based on their brightness, specificity, and compatibility with the instrument’s lasers. High-dimensional panels work best with dim fluorochromes for bright antigens and bright fluorochromes for dim antigens.
- Identify the markers of interest for the high-dimensional panel.
- Select fluorochrome conjugates based on their brightness and compatibility with the available lasers.
- Optimize the panel by testing and adjusting the combination of fluorochromes to achieve the best possible resolution and minimal spectral overlap.
